Endoscopic Ultrasonography

Endoscopic Ultrasonography or EUS is a state of the art technology we are proud to make available to the residents of New Hampshire and surrounding communities.

As the name implies, this procedure combines endoscopy and ultrasound. As in traditional endoscopy, a flexible endoscope is inserted into the GI tract through either the mouth or the rectum providing capability to view the intestinal lining. The ultrasound probe located on the endoscope further provides unparalleled images of internal organs, lymph nodes and other structures by utilizing sound waves. These same images may not be detectable by traditional CAT scan or MRI. Images can be photographed or videotaped as high-resolution pictures and if needed, tissue samples or biopsies of suspicious looking growths are possible. EUS is very safe and does not employ any radiation, only sound waves.

EUS is particularly useful in the diagnosis of cancers and if found, determining the depth of invasion into surrounding tissues. Some examples of conditions where EUS is helpful include cancers of the esophagus, pancreas or rectum. In these situations, EUS may determine how much surgery is necessary as well as whether surgery is likely to cure the underlying disease. EUS is also useful in identifying many non-cancerous conditions such as abnormalities of the pancreas and bile ducts and since EUS technology is still in its infancy, we expect even more uses for diagnosis and therapy in the future.

EUS is performed in an outpatient setting under sedation with a brief recovery period following the exam. The procedure itself requires approximately 30 minutes. After the exam, patients can typically expect a two (2) hour stay in the short stay unit. You will need a ride home from the hospital after your procedure.

EUS is currently being performed at the new Wentworth Douglass Hospital endoscopy unit by Dr. Jaime A. Baquero. Dr. Baquero has most recently trained at the Lahey Clinic in Burlington, Massachusetts to become expert in EUS procedures. Dr. Baquero will work closely with you and your physician to ensure you are receiving the best possible care and treatment.
